Airtac MFD Double Rod Miniature Cylinder MFD20X80S
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD20X80S is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø20mm bore and 80mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFD Double Rod Miniature Cylinder MFD20X80S
Twin rods exiting both covers define the AirTAC MFD20X80S, a JIS-standard round-body mini cylinder built for equal push and pull thrust. Because the piston uses the rod-side area in both directions, you get 131.9 N of force at 0.5 MPa and 184.7 N at 0.7 MPa each way. The SUS304 stainless barrel shrinks mounting length compared to an ISO 6432 unit while resisting mild washdown corrosion.
The built-in magnet (-S) enables CMSG, DMSG or EMSG switches for position feedback. With a safe working load around 79 N (60% of the 0.5 MPa rating), it handles about 6.7 kg vertically per direction with a 2:1 margin. The 1/8 inch port, M8x1.25 male rod thread, and fixed TPU bumper pads round out this 80 mm stroke build.

Where the Airtac MFD Double Rod Miniature Cylinder MFD20X80S Is Used
Twin-Tool Transfer
Shifts a secondary gripper on the back rod to cycle a 6.7 kg payload horizontally without adding a separate cylinder.
Anti-Rotation Guide
Keeps a small pick-and-place head steady over an 80 mm stroke, using the dual 8 mm rods to resist torsional side-play.
Dual-End Switching
Uses the -S magnet with EMSG sensors to flag both extend and retract positions for a precise 131.9 N clamping routine.
Is the Airtac MFD Double Rod Miniature Cylinder MFD20X80S the Right Cylinder?
When choosing between the two available bores, the MFD20 delivers 131.9 N at 0.5 MPa while the larger MFD25 offers 206.1 N. Pick this 20 mm bore for lighter anti-rotation slides where a single rod would let the load twist. The twin rods steady the payload and provide a second end for mounting a stopper or switching flag.
This -S SKU includes the piston magnet needed for CMSG, DMSG or EMSG sensors; a non-S SKU cannot take a switch. Note that fixed TPU bumpers only decelerate the stroke end—the piston drifts on air loss, so add an external rod lock or pilot check valve to hold a suspended load. Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover code exists on a double-rod build).
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFD Double Rod Miniature Cylinder MFD20X80S FAQ
It delivers equal force both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical max of 26.9 kgf at 1.0 MPa. The air port is 1/8 inch and speed ranges 30-800 mm/s.
The twin 8 mm rods provide equal thrust both ways and resist load rotation. It does not hold position on air loss—the fixed TPU bumpers only decelerate ends, so use an external rod lock for suspended loads.
